Nonbrowning Zoom Lens

The Model 357 non-browning zoom lens from Resolve Optics Ltd. provides true HD-quality images and a 10× zoom range.

Using specialist non-browning glasses, the Model 357 is able to produce clear, sharp images, free of the strong yellow tint that has traditionally been a limiting issue when using radiation resistant lenses on color sensors. The Model 357 HD 10× zoom lens has been designed to operate in environments subject to high levels of radiation such as nuclear fuel handling, reactor active zones and nuclear waste storage plants. The specialist nonbrowning glass is proven to withstand long-term exposure to radiation up to a dose of 100,000,000 radians and temperatures to
55 °C without discoloration.

Operating at f/2, the Model 357 provides high image resolution and minimum geometric distortion from 400 to 770 nm, and can image objects from 800 mm to infinity without using add-on adapters.
